Marketing is a pretty broad field. In an MBA course, the book can be 900 pages long. From the identification of customer groups, the design of products, communication, access to the market, advertising measures, the strategy in competition, much more belongs to it.
But there is a point in time when marketing should stop. That is when a customer shows interest in a product. That's when empathy needs to come out. You simply don't know why a customer is interested in a product. It could be reasons that are far beyond one's imagination.
Ryan Serhant wrote in his 2018 book that he had a client who was interested in sales training. Not because his department needed it. No, the department was by far the best in the entire company. Sales training was the only way in the company to organize an offsite with a party character. A way to have some fun.
